If everybody was put under home quarantine for 3 weeks. Aside from those needing hospital treatment or working in hospital.
(I assume PP also still wants people running electricity, gas, phone & water networks to still go to work, too)
I guess that means...
no walks for dogs
no one to deliver food if you don't already have enough (or bog roll)
no carers to go to homes of vulnerable folk
no police doing anything
no firefighters
no telly or radio broadcast (their non-essential staff can't get to work)
many farm animals dying from lack of attention
no policitians or scientists telling us what's going on (maybe a good thing)
no scientists or public health managers recording what's going on, no surveillance (maybe ditto)
nobody cleaning public toilets
no public transport
no petrol stations open
could work if you locked all the carers & NHS staff into their places of work, maybe
Lots of quiet places for criminals to sneak around
